A quick change device is adaptable for use on a reciprocating press fin machine which continuously forms a metal sheet into sinuous or corrugated configuration by using tools associated with upper and lower opposed, metal-engaging tools, each movable toward and away from the other in a vertical forming stroke, and a first one of these tools also being movable in a variable stroke transverse to its vertical forming stroke. Wedge-shaped abutment elements and associated block elements having a wedge-shaped cavity therein adapted to receive the abutment elements, establish the length of transverse motion of the first tool. A structure is used to simulate the reciprocating press fin machine. A reader assembly digitally analyzes movement of the wedge-shaped abutment elements to set the transverse stroke length, based on the simulation provided by the structure, to allow precise alignment of the tools in the reciprocating press fin machine.
